This invention relates to a unit for heating, cooling and Ventilatingsystems, the general object of the invention being to provide a memberhaving passages so arranged therein that air or the like can passthrough one set of assages without contacting with air or the likepassing through the other set of passages, whereby the iuid passingthrough one set of passages will change the temperature of the fluidpassing through the other set. l

This invention also consists in certain other features of constructionand in the combination and arrangement of the several,

parts, to be hereinafter fully described, illustrated in theaccompanying drawings and specifically pointed out in the appendedclaims. r

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like'characters denote like orcorresponding parts throughout the several views, and in which Figure 1is a sectional view showing the invention used as a ventilator.

Figure 12 is a view showing the invention used for heating the cold airentering the fire box of the furnace by the products of combustionpassing from the furnace.

Figure 13 is a view showing fans used for creating a forced draft inboth sets of air passages. l

Referring to Figures 1 to 5, the numeral 1 indicates a casing passingthrough an o ning 2 in a wall 3 of a building, this casing aving a pairof upper and lower openings 4, 4 in each end thereof, the openings 4being in communication with the interior of the building and theopenings 4-with the atmosphere. A pairof rectangular housings 5 and 5 isplaced in the casing, one at each end thereof, each housing beingydiagonally positioned, Vwith its upper-and lower corners attached to theinner wall of the upper and lower openings, as shown at 6,v and with itsouter corner attached to each end of the casing, as shown at 7 Apartition plate 8 connects the inner corners of the two housingstogether,.so that this partition plate and portions of the housings formupper and lower chambers 9 in the casing. Each housing is divided by thepartitions l0 into two sets of passages 11 and 12,- one set of passagesbeing arranged at right angles to the other set, with one set ofpassages vof each housin being in communication with the lower c amber 9and the other set being in communication with the upper chamber 9, thepassages which are in communication with the upper chamber 9 being alsoin communication with the lower openings 4, 4 and the passages which arein communication with the lower chamber 9 are in communication with theupper openings. Thus the foul air from the building will pass throughthe upper lopening 4 through the passages 11 of the housing 5 into thelower chamber 9 and through the passages 11 of the housing 5 to theatmosphere throu h the upper opening 4. Cold air will pass t rough thelower openin 4 through the passages 12 in the housing 5 into the upperchamber 9 and then this cold air will pass through the passages 12 inthe housing 5 and will .enter the building through the lower opening 4.This cold air is heated as it passes throu h the device by coming intocontact with t e heated walls of the passages which ing an air supply toa have been heated by the ow of warm foul air from the building. Asshown in Figures 3, 4 and 5, the sides of the passages 12 are closed bythe strips 13 which are connected with the ends -of every other pair ofpartitions l0 and the sides of the passages 11 are closed by similarstrips.

Thus it will be seen that I have provided simple means for not onlysupplyin a'building or the like with fresh air an e]ect1n(gi the warmfoul air, but I have also provide means whereby the inflowing cold air1s heated by the outiiowing warm air.

Figures 6, 7, 8, 9 and 1() show a slight modiiication, in which ahousing 14 replaces the two housings 5 and 5', the ends of this housing14 being tapered, as shown at 15, with the partitions 16 forming the airpassages 1n the housing also tapered. Strips 17 close the ends ofalternate passages on one side of the tapered portion and similar strips17 close the ends of the other alternate passages on the opposite sideof the tapered portion, so that theends of one set of passages open outthrough one side of each tapered portion and the other set o en outthrough the other side of each tapere portion. Thus by connecting two ofthe side portions of the tapered parts of thehousing with two conduitsand the other parts of the tapered portions with other conduits, airwill flow in an opposite direction through the other set of passages.Figure 6 shows this arrangement used for heatfurnace Al by the productsof combustion from the furnace. The housing is shown at 14, with one setof passages opening out into the atmos here, as shown at 15, and theopposite set o assages being connected with the smoke ipe 6 ofthefurnace. The set of passages w 'ch are connected with the smoke pipe arealso connected with a chimney, portion of which is shown at i 17, andthe other.set of passages is connected i .es

by a conduit 18'with the ash it or iire box of the furnace. Thus theprodliicts of combustion passing through one set of passages will heatthe atmospheric air passing through the other set of passages so thatthis air will be heated before it enters. the furnace, thus increasingthe combustion of the fuel. Figure 7 shows a housing 14 used asventilating means, in which the fluid passes. in opposite directionsthrough the passages, this arrangement being somewhat similar to thatshown in Figure 1.

Figure 11 shows a housing 14" used for Ventilating a building which isheated by a hot air furnace A', the outer ends of one set of' passagesbeing in communication with an air pipe 19, and the outer ends of theother passages being in communication with a discharge pipe 20. Theother ends of the passages which are connected with the pipe 19 areconnected by a 21 with the air chamber of the furnace and a conduit 22leads from a register 23 in the floor of the room above the furnace roomto the inner ends of the passages which are in communication with thedischarge 20. Thus heated air will pass from the room or buildingthroughthe register 23 and the conduit 22 and through one set of passa es inthe` housing 14'( to the discharge 20 and fresh air will enter throu hthe pipe 19, the other set of passages in t e housing 14 into the pipe21 and thus enter the hot air chamber of the furnace and then pass intothe building. In this way, the building or room is provided with freshheated air, this air being heated by the foul warm air leaving thebuilding or room.

Figure 12 shows a similar arrangement for supplying warm air to the firebox of an oil burning furnace A the products of combustion from thefurnace passing `through one set of passages in the housing 14x to thechimney, and air passing through the other set of passages in saidhousing 14x into the pipe 24 which leads it to the fire box of thefurnace. Thus the air passing to the furnace is heated by the productsof combustion therefrom.

Figure 13 is a modification showing the use of a fan 25 in each of theinlet members 19 and outlet member 20', these fans being arranged on thesame shaft 28 which is driven by a motor 27. These fans act to force airthrough the device and to draw the warm air or products of combustionthrough the second set of passages in the device.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts, provided thatsuch changes fall within the scope of the appended claims.
